Passive House and the RIAI Climate Challenge

Speakers: Tim Martell & Helena McElmeel

Tim is an AECB Expert Advisor and an expert in CO2 calculations for buildings. He qualified as a Passivhaus Designer in 2012 and worked on new build, retrofit, domestic and commercial PHPP models. For several years he contributed data for the AECB Retrofit course. Later he also qualified as a Retrofit Coordinator and coordinated 90 retrofits in London. Four years ago he started developing the AECB’s PHribbon software, combining his experience in PHPP with earlier work in research and as a programmer. Tim saw a great need for Embodied CO2 calculations that could be easily done in PHPP. He has continuously improved the software ever since, given many talks on it, and there are now Canadian and US versions.
